The mounting plate I is preferably ametal stamping or pressing and is illustrated as such, although in some apparatus the use of a diecast mounting plate may be envisaged. I

A reciprocatingpumpety'pe charge-dispensing mechanism is incorporated in the lower portion of the storage receptacle 6. An inlet port 21in the.floor.l5 of the receptacle 6 communicates with the. interior of a cylinder 22 within which a piston 1 21 is adapted ,to reciprocate. The piston .27 is biased rearwardly withincylinder 22 by a coiledcompression spring 28 encircling said piston and interposed between therear face 29 of the cylinder and a collar 30 on the .rear extremity of the piston. The-resistance of spring 28' is overcomehy pressure applied to the piston collar 30' through an operating handle .31

The; lugfill'aand the hole.4l are so dimensioned: and positioned thatthezstorage receptacle 6 cannot be slidupwardly with respect to thernounting plate lto disengage the slide surfaces Zand S whilelthe lid 8 is in position on the storage recep:

tacle vwhenthe bolt 38 is engaged in within the recess 39 the i lid 8 cannot be removed from the storage receptacle 6. To remove the lid, the key is inserted in the lock 37 and turned to release the bolt 38 from within the recess 39, whereupon the lid 8 can be removed by lifting forwardly and upwardly to withdraw the lug 40 from within the hole 41 in the mounting plate 1. The storage receptacle 6 may then be recharged without need to detach it from the mounting plate 1, although it may readily be detached in the manner described if it is desired to service the charge-dispensing mechanism or alter the setting of the mechanism.

It will, of course, be appreciated that the lock 37 and the lug 40 may be interchanged if desired, namely so that the lug 40-.

effects locking interengagement within the recess 38 and the lock-37 locks the lid directly to the mounting plate 1 instead of and disengaged from said mounting plate by an endwise relative sliding movement, a lid for said storage receptacle, said lid 'ueing removable to enable said storage receptacle to be charged, and locking means including a key-operated lock fitted in said lid for locking said lid to said storage receptacle and a lug provided on said lid to effect locking interengagement with said mounting plate, whereby removal of said lid from said storage receptacle and said relative sliding movemerit to detach'said' storage receptacle from said mounting plate are prevented so long as said lid is locked, wherein said storage receptacle includes an integral floor portion and said exteriorly operable means comprise an operating handle pivotallymounted from said floor portion and adapted when swung forward to actuate said charge-dispensing mechanism in said lower portion of said storage receptacle.

2. A dispensing apparatus as claimed in claim 1, wherein said charge-dispensing mechanism includes means rendering it selectively settable for varying the charge of substance dispensed. V

3. A dispensingapparatus as claimed in claim 1, wherein said lid and said storage receptacle are metal die-cast body members.

4. A dispensing apparatus as claimed in claim 1, wherein said lock is a cylinder tumbler lock.
